Yann Collet 75bcae1272 removing x32 tests 
this ABI is no longer supported by Ubuntu,
and there is a wider consensus that this ABI is on the way out,
with more and more distributions dropping it,
and lingering questions about support of x32 in the kernel.

 2025-02-09 11:38:44 -08:00
Yann Collet aebffd66ec --ultra automatically triggered with --long and --patch-from 
the purpose of --ultra is to make the user explicitly opt-in
to generate very large window size (> 8 MB).

The agreement to generate very large window size is already implicit
when selecting --long or --patch-from.

Consequently, `--ultra ` is automatically enabled when `--long` or `--patch-from` is set.

Yann Collet e117d79e22 fix minor alignment warning 2025-02-05 16:13:58 -08:00
Yann Collet c39424ea87 fix minor alignment warning 
this is a prototype definition error:
`_mm_storeu_si128()` should accept a `void*` pointer,
since it explicitly states that it accepts unaligned addresses
yet requiring a `__m128i*` tells otherwise, and requires the compiler the enforce this alignment.
 2025-02-05 16:11:54 -08:00
Yann Collet 32dff04d32 fix one minor alignment warning 
seems like a prototype interface error:
input parameter should have been `const void*`,
since the documentation is explicit that input doesn't have to be aligned,
but `const __m256i*` makes the compiler enforce it.
 2025-02-05 15:46:44 -08:00
Yann Collet 5883ee6cc2 make visual studio tests error out on warnings 2025-02-05 15:38:39 -08:00
Yann Collet 54e9d46db4 added __clang__ to compiler-specific alignment attribute 
when clang is used within msvc, `__GNUC__` isn't defined,
so testing `__clang__` explicitly is required.

Yann Collet 60f84f73fe bench: better result alignment 
when displaying ratios > x100
 2025-01-30 21:30:48 -08:00
Yann Collet 82346b92bb minor: generalize BitContainerType 
technically equivalent to `size_t`,
but it's the proper type for underlying register representation.

This makes it possible to control register type, and therefore size, independently from `size_t`,
which can be useful on systems where `size_t` is 32-bit, while the architecture supports 64-bit registers.

Yann Collet 9efb09749b added a CI test for x86 32-bit + avx2 combination 
which is expected to be quite rare, but nonetheless possible.

This test is initially expected to fail, before integration of #4248 fix
 2025-01-18 22:49:16 -08:00
Yann Collet e8de8085f4 minor: assert that state is not null

Yann Collet 4f3311f245 CI: replaced shortest target by check 2025-01-18 12:24:11 -08:00
